Carson Daly and Jimmy Fallon's moms were friends for 13 years before their deaths: See the touching pic

Carson Daly revealed on Tuesday that his mother and Jimmy Fallon's mother, who died within two months of one another, were close friends.

Daly Instagrammed a touching pic of his late mom, Pattie, and Fallon's late mom, Gloria, together, both smiling and holding flowers. The Today co-host wrote that the two met in 2004 and remained pals ever since.

"My mom & @jimmyfallon’s mom Gloria met in 2004 on Letterman’s top 10 Mother’s Day list," the caption reads. "They would become fast friends. A NY visit would later always include lunch w Gloria. They had a blast together. I know they’re above proud, laughing & shinning light on their boys. Hang tough pal."

"When we were little, my mom would walk us to this store, me and my sister, and she would squeeze my hand three times and say, ‘I love you,’ and I would squeeze back, ‘I love you, too,'” the host recalled, holding back tears.

"Last week I was in the hospital and I grabbed her and squeezed 'I love you.' I just knew we were in trouble, you know?" he continued. "I feel so grateful to be able to do this every single night and I’m very appreciative of all the support from all of you that my family received over the past week. We’re going to continue to work really hard to bring some light and some laughter into the world. Thank you for watching, thank you for helping me and my family recover from this loss. Mom, I’ll never stop trying to make you laugh. I love you."

Taylor Swift made a surprise appearance for Fallon's return, performing her new single, "New Year's Day." Coincidentally, the lyrics include the line, "You squeeze my hand three times in the back of the taxi."

Questlove, a member of Fallon's in-house band, The Roots, tweeted about the stunning coincidence on Monday.

"I’m just realizing Taylor didn’t readjust the song’s lyrics for tonight’s performance," he wrote. "But the narrative literally applies to the words Jimmy spoke of his mother. Wow. You can’t plan these things @taylorswift13 @FallonTonight."
